The present invention relates to driving mechanisms for motor vehicles, and embodies, more specifically, an improved bearing support for the driving shafts of a motor vehicle employing a plurality of driving axles.

differential for dividing power between a plurality of driving axles, the third differential being mounted forwardly of the axle.

In driving mechanisms of the above character, difficulty has heretofore been encoun- 1 tered in assembling the units in such a manner as to provide adequate strength as well as an accessible and readily serviced unit. \Vith the foregoing in view, it is an object of the present invention to provide a drive of the above character wherein the carrier as sembly of an axle is a self-contained unit. This is of material advantage over the old system of mounting the outboard pinions in covers attached to the rear of the banjo, thus sacrificing proper alignment, etc.

A further object of the invention is to provide a bearing support which is formed upon the axle banjo in such a manner as to mount, accurately, the bearings for the through shafts and further provide a bearing sup-port for the differential bearings.

A further objectof the invention is to pro vide a construction of the above character which is a complete unit including a differential gear, a hypoid gear, and through shaft, such unit being completely assembled before being inserted into the banjo.

Further objects, not specifically enumerated above, will be apparent as the invention is described in greater detail in connection with the accompanying drawings, wherein:

Figure 1 is a View in longitudinal section taken on line 11 of Figure 2 and looking in the direction of the arrows.

Figure 2 is a view in section taken on line 22 of Figure, 1 and looking in the direction of the arrows.

Referring to the above drawings, driving flange 10 is connected to a power source through the universal joint in any well known fashion, and drives the splined stub shaft ll through its hub 12. The hub 12'is journalled at 13 in acover plate 14 secured to a third differentialhousing15. i

' Within thehousing15,a cylindrical spider 5:;

16 is mounted.-' This spider is "formed on a disc 17 which is secured to'thesplined stub shaft 11 and carriesa series of wedges 18 of suitableforn'ifwith radial apertures within cured to the spider and serves as a means for preventing the escape of lubricant from the differential mechanism. The type of dilferentialmechanism" contemplated herein is as describedin the'co pending application of Azor D. Robbins, Serial No. 447,463, filed April 26, l930,' an'd theprcsent application is a divisional application thereof. 1 The external cylindrical driven member 20 is'formed with cam tracks against which the Wedges '18"e1igage cooperating in this fashion witlrsimilarly formedtracks upon the internal driven member 21. The driven meniber 20 is splined at 22 to a pinion shaft 23,

sion 25- of the housing-1'5. The internal driven member 21"i s splined to the through shaft 26 Whichdrives the flanged member 27 thecylindri'cal spider. The cover 19 is seas which is journalled at'24 within the extento-c'arrythe drive rearwardly to a second driven axle.

Secured to'the radial flange 28 on the housing 15-is a cage'29,formed with a flange 30. This cage forms the forward housing portion the final idri've'fo'r the ackshafts 31, these jackshafts being carried by'axle 32. A banjo 33 is' formed-on the axle 32. Against this banjo; the flange 30 is secured, as clearly shown in Figure 1.." V

Cage 29 is' formedwith bosses 84, to which bosses 35 are secured. Bosses 35 are formed integral with the rearwardly extending-arms 36, a bearing supporting'member 37 being formed on thearms 36. Within the bearing supporting member 37, a'bearing 3 8 is receiv'ed;thisbearing'being journalled to the rearward extremity of the through shaft 26.

The pinion shaft 23 is formed with a pinion 39 which drives the ring gear 40 of the differential mechanism 41, these elements being of standard form. The differential mech- From the foregoing, it Will be seen that a construction has been provided by means of f which the driving elements ofan axle may be assembled as a unit before being mounted upon the axle. It will be further noted that the cage and bearing su porting means, described above, is particu arly well suited for use in connection with the third differential for apportioning power between a pluralit of driving axles.

While the invention has been described with specific reference to the accompanying drawings, it is not to be limited, save asdefined in the appended claims. I claim as my invention:

1, A mounting of the character described 7 I comprising a cage forming housing for a differential, means carried by the cage for journailing a powershaft, an arm on the-cage, and a bearing on the arm aligned withthe journalling means, and a housing mounted over a portionsof the cage and cooperating with a portion thereof to one a closure forthe-difterentinl.

2. A mounting of the character describe comprising acage, rearwardly extending arms on the cage, hearings on the arms for journalling a (inferential mechanism, a bearing on the cage for a power shaft and a bearing on the arms aligned with thelast named bearing for a power shaft, and a cover for the arms. 1

3. A mounting of the diameter described comprising a cage, rearwardly extending r. J v

arms on the cage, hearings on the arms for ournalhng apdrfferentlal mechanism, a. bearmg on the cage,abearmg on-the arms aligned with the last named bearing, a cover for the arms, and a flange on the cageadapted to be secured to the banjo portion of an aide.

4. A mounting of the character described comprising a cage, rearwardly extending arms on the cage, hearings on the arms for journalling a differential mechanism, a differential housing mounted on the cage forwardly thereof, a. bearing in the housing, a bearing on the arms aligned with the last named bearing, a cover for the arms, and a flange on the cage adapted to be'secured to the banjo portion of an axle.
